General product information

The composed system is a compact, portable measurement system for recording and transferring analogue and digital signals. It consists of a data logger (see Suitable data loggers) with installed IoT application "4-Channel Data Logger". To simplify matters, the measurement system will be referred to as "4-Channel Data Logger " hereinafter. Depending on the power supply unit used, the 4-Channel Data Logger can also operate without mains power. The device is equipped with 4 universal inputs that can be operated in various analogue and digital modes. In addition, an interface for connecting a PT100 or PT1000 is available following the chargeable release (Activation code temperature input ,300542). The device automatically detects which of the two types is being used. The 4-Channel Data Logger is also equipped with internal sensors (internal housing temperature and air humidity in the housing), 2 switchable voltage outputs to supply the sensors and an isolated switch contact to directly control an actuator. The output voltage for one of the two switchable sensor supplies can be set to 14,7 V or 23,4 V via the input screen for configuring the output channels (see Output channels). The output voltage for the other switchable sensor supply is 3,3 V and cannot be changed. All output channels can be configured independently so that they can each be switched by the device itself prior to a measurement (to supply a sensor) or so that they can be switched wirelessly from a central location. The isolated switch contact can also be operated in different modes (frequency, PWM, pulse/min.). All of the input measurement data is temporarily saved to an internal data memory along with the output states and wirelessly transferred to a central location at a freely selected interval. The device is also configured via this connection. The device is equipped with an integrated SIM chip.
